Elaine has a $25 gift card. She uses the card each
month to purchase a magazine for $3.50 at the
bookstore. How much money will Elaine have
remaining on her gift card after 7 months?
Answer:
$0.50
Step-by-step explanation:
multiply 3.50 by 7 and you get 24.5. $25.00-$24.50= $0.50
Answer:
0.5
Step-by-step explanation:
Well lets start with a basic equation.
$25=3.50(7)
25= 24.5 multiply 3.50 and 7
25-24.5=0.5 subtract the total from the whole
After using the card for 7 months she will have 5 cents left on her card.

In Phoenix, Arizona, the average temperature is 85 degrees Fahrenheit or higher during 25% of the year. During about how many weeks of the year is the average temperature below 85 degrees Fahrenheit?
Answer: 39 weeks
Step-by-step explanation:
Given
The average temperature is [tex]85^{\circ}F[/tex] or higher
A year has 52 weeks
It is given 25% of the time-temperature is above [tex]85^{\circ}F[/tex]
So, in the remaining 75% of the weeks, the average temperature is less than [tex]85^{\circ}F[/tex]
No of weeks can be determined by
[tex]\Rightarrow 75\%\ \text{of}\ 52\\\\\Rightarrow \dfrac{75}{100}\times 52=39\ \text{weeks}[/tex]
Find the perimeter of quadrilateral ABCD with vertices A=(1,1) B=(4,4) C=(7,1) D=(4,-2). Explain your answer.
we have the coordinates of ABCD
there are 2 ways of doing this one is you find the distance of ab, bc, cd and da and then add the answers together. there is another way but i dont remember it properly so i am just gonna do it this way
distance between 2 point = [tex]\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}[/tex]
AB
[tex]d = \sqrt {(4 - 1)^2 + (4 - 1)^2}[/tex]
[tex]d = \sqrt {(3)^2 + (3)^2}[/tex]
[tex]d = \sqrt {9 + 9}[/tex]
[tex]d = \sqrt 18[/tex]
AB = 4.24
now repeat the same with all
BC= 4.24
CD= 4.24
DA= 4.24
so its a square with all the same sides so perimeter is 4 x 4.24
perimeter is 16.96

Integer Quotient Problem
Two positive integers have a sum of 92.
If the larger integer is divided by the smaller one, the quotient is 3
and the remainder is 12. What are the two integers?
Suppose that we have x and y as the integers( x is bigger than y ).
As the question told :
x = 3y + 12
_________________________________The integers have a sum of 92 which means :
x + y = 92 ==》( 3y + 12 ) + y = 92
==》 4y + 12 = 92
==》 4y = 92 - 12
==》 4y = 80
==》 y = 20
☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆
x + y = 92 ==》x + 20 = 92
==》x = 92 - 20
==》x = 72
Answer:
The two integer is, y = 20 and
x = 72
Step-by-step explanation:
Definition of integer:Integer, positive or negative whole number, or 0 The integers are created using the counting numbers 1, 2, 3,... and the subtraction function. The result of subtracting a counting number from itself is zero; for example, 4 4 = 0. When you subtract a greater number from a smaller number, you get a negative whole number; for example, 2 3 = 1. Every integer may be deduced from the counting numbers in this fashion, resulting in a set of numbers that can be subtracted.
As the question told :
x = 3y + 12
The integers have a sum of 92 which means :
x + y = 92
= ( 3y + 12 ) + y = 92
= 4y + 12 = 92
= 4y = 92 - 12
= 4y = 80
y = 20
Then, x + y = 92
x + 20 = 92
x = 92 - 20
x = 72
The two integer is, y = 20 and x = 72

1 pts The function f(x) = 12,900(0.40)x models the population of ants in a house x days after their discovery. Which statement describes the population of ants?
Answer:
f(x) = 500 • 1.1x
Step-by-step explanation:
To solve the question, we need to understand that:
- The population of ants is going to increase with time as they mate and have a population positive growth rate.
- The initial number of ants is 500.
- The rate at which it increases will be multiplied with x months
We will work our way out by removing the wrong answers first
Since,
The population cannot be decreased so we can neglect the last two options involving 0.9 as it will result in a decrease in the population.
Now we are left with two options:
a) f(x) = 500 • 1.1x
b) f(x) = 1.1 • 500x
Since in the option (b) , 500 is multiplied with x , it is not possible as 500 is a constant initial amount and not a factor of growth of population. The growth factor is supposed to be multiple of x months.
So, the correct answer is f(x) = 500 • 1.1x

Two angles form a linear pair. The measure of one angle is eight
times greater than the measure of the other angle. Find the measure
of the bigger angle only.
Answer:
160
Step-by-step explanation:
Givens
Let the smaller angle = x
Let the larger angle = 8x
Equation
x + 8x = 180 Combine like terms
Solution
9x = 180 Divide by 9
9x/9 = 180/9
x = 20
Answer
The larger angle = 8 * 20 = 160

x/3-300=250 Show your work
Answer:
x=1650
Step-by-step explanation:
1650/3=550-300=250
Answer:
x = 1650
Step-by-step explanation:
We are given the equation x/3 - 300 = 250 and are asked to solve for x.
To solve this, we need isolate x, do as followed :
x/3 - 300 = 250
Add 300 to both sides :
x/3 = 550
Multiply 3 to both sides :
x = 1650
